Let's see...Sound, picture...no text?! Oh, I'm going to have to 1 you for that.

But seriously. Good synchronization, as the gif starts over just where the sound starts over, the right way. Since anything smaller than a 5 would be a downvote, I grant you a 5.

Timing is everything. Which is why I will say, I love this, but please get it to loop better. I guess you're using an MP3 now because of the preloader, but I think the loop would be worth dodgy sync. I really didn't care about the sync.
